' JNVENTORS- 66641.0 P M CA/V/V FE/WK F CHASE ATTOE/VVS LIQUID-DISPENSING DEVICE WITH AUDIBLE ALARM This invention relates to liquid-dispensing devices, and more particularly to such devices particularly useful in the dispensing of liquors and for providing a signal upon dispensing thereof.

There is an increasing desire to provide a suitable device for monitoring the dispensing of liquids from bulk containers. In particular, dispensing of liquors in bars and similar establishments is susceptible of abuse. Several approaches to counting or monitoring dispensing, such as described in U.S. Pat. Nos. 2,754,034, 2,883,086 and 3,170,597, have been made. The latter patent illustrates a liquid dispenser which may be attached to a bottle and which includes a radio transmitter for transmitting signals to a radio receiver and recorder. There are several factors which must be considered in providing such devices inasmuch as any given establishment may employ a large number of dispensing and monitoring devices and, thus, the size, weight and cost of each device must be within practical limits to enable the use thereof to be economical.

Accordingly, it is a principal object of the present invention toprovide an improved liquid-dispensing device of relatively simple construction and which emits a detectable signal each time liquid is dispensed thereby.

It is an additional object of this invention to provide a device attachable to a bottle for dispensing liquid therefrom and which emits detectable vibrations upon dispensing of liquid.

A further object of this invention is to provide a liquiddispensing device for dispensing predetermined amounts of liquid and providing a signal, such as subsonic, sonic or ultrasonic, each time such liquid id dispensed.

These and other objects and features of the present invention will become better understood through a consideration of the following description taken in conjunction with the drawing in which:

FIG. 1 is a cross-sectional view of a dispensing device constructed in accordance with the teachings of the present invention;

FIG. 2 is another view, partially in cross section, of the device shown in FIG. 1; and

FIGS. 3 and 4 are cross-sectional views illustrating an alternative form of dispensing device employing a reservoir.

Turning now to the drawing, a dispensing device according to the present invention may be secured within the mouth of a bottle 10, and includes a positive displacement pump 11, pouring spout l2, and vibrator 13. An operator button 14 is provided for operating the pump 11, and for causing a hammer 15 to strike the vibrator 13.

Considering the device in more detail, a resilient plug 17 is provided for sealing the device with the mouth of the bottle 10. The plug 17 is afiixed to the body 18 of the dispensing device. A tube 19 is secured to the body 18 and extends downwardly through the plug 17. A lock arm 20 is affixed to the lower end of the tube 19, and a rotatable lock arm 21 extends downwardly through the tube 19 and is operated by a keylock 22 in a conventional manner. As a key 23 is turned to a lock position, the arm 21 rotates to the position shown in FIG. 1 to prevent withdrawal of the dispensing unit from the bottle 10.

The body 18 includes a chamber 25 forming a cylinder for a piston 26. The cylinder 25 and piston 26 form the pump 11. An actuator arm 27 extends between the piston 26 and the operator button 14. An O-ring 28 is provided on the piston 26 to provide a suitable seal. The piston 26 is biased to the position shown in FlG. 1 by a spring 30.

Liquid is supplied to the pump by gravity through a check valve 32 mounted in a lower chamber 33. The plug 17 has an aperture 34 communicating with a passageway 35 in the body 18 so as to allow liquid to pass from the bottle 10 past the check valve 32 to the pump chamber 25 when the bottle and dispensing unit are tipped for pouring. In this manner, liquid from the bottle 10 flows by gravity past the check valve 32 into the pump chamber 25. An outlet check valve 37 is mounted in a chamber 38 and communicates between the pump chamber 25 and an outlet passageway 39 in the-pouring spout 12. It will be apparent that depressing the button 14 moves the piston 25 to the right as seen in FIG. 1 thereby forcing the liquid from the pump chamber 25 past the check valve 37 and out the pouring spout 12. A venthole 40 is provided through the body 18 to vent the back side of the pump piston.

The button 14 includes an actuator or trip finger 42 which extends into an aperture 43 in the body 18 when the button 14 is depressed. The hammer 15 is mounted on a leaf spring 43 which is secured in the body 18 at 44. The vibrator 13 is secured to a resilient member 45 which in turn is secured to the body 18 at 46 by means of a screw fastener or the like. A shock pad 47 is provided behind the hammer 15. The vibrator l3 and hammer 15 are mounted within a cavity 48 in the body 18. As will be apparent to those skilled in the art, the body 18 can be made of two or more parts to facilitate assembly of the components of the dispensing device.

Depression of the button 14 causes the finger 42 to engage the spring 43 which in turn moves the hammer 15 into engagement with the vibrator 13. The vibrator 13 thus is struck by the hammer 15 and vibrates at a frequency depending upon the mass and mounting of the vibrator. The vibrations may be sensed or recorded in a variety of ways, such as by direct listening, by use of vibration and frequency sensitive relays, recorded on tape, sensed and rebroadcast, and so forth. Sensing arrangements such as those illustrated in U.S. Pat. No. 2,821,954 may be employed.

Different vibrators emitting different frequencies may be provided for different types of liquors, such as one frequency for bourbon, one frequency for gin, and so forth, thereby providing different frequencies for these different types of liquors. In a typical application, frequency selective receiving circuits can be employed to receive the vibrations from respective dispensing units so as to count or otherwise record the-number of drinks dispensed.

In operation of the present dispensing device, the operator tilts the liquid container bottle 10 so as to cause the liquid to flow by gravity past the inlet check valve 32 into the pump chamber 25. The operator applies force on the button 14. This force is resisted by a detent 50 mounted in the body 18 such that the force-displacement curve has a decreasing characteristic. That is, the force applied by the operator must reach a predetermined minimum value in order to initiate the movement of the button 14. In the course of actuation, the force required to continue the actuation decreases from the predetermined minimum, thus producing a rapid motion. The actuation causes the liquid in the pump chamber 25 to flow past the outlet check valve 37 and to be dispensed from the pouring spout 12. The actuation simultaneously causes the hammer 15 to strike the vibrator 13 and the latter to vibrate. As noted above, the construction of the vibrator 13 may be different for different types of liquids. Thus, each time the predetermined amount of liquid is poured, the vibrator 13 is struck thereby providing a signal indicative of dispensing of one portion of the liquid. The vibrations may occur at any municate througha ball check valve 32 to a passageway 56.

The passageway 56 communicates with the reservoir 55, which in turn communicates through a ball check valve 57 in a chamber 58 with the pump chamber 25. When the unit is tipped for pouring, as seen in FIG. 4, the liquid is expelled by the pump 11 past the check valve 37 to the pouring spout 12 and, at the same time, liquid flows by gravity past the check valve 32 and through the passage 56 into the reservoir 55. When the unit is again moved to the upright position as seen in FIG. 3, liquid from the reservoir 55 flows into the pump cavity 25. This arrangement ensures that the pump chamber 25 is full of liquid at the start of each dispensing operation. Preferably,

the reservoir 55 has a capacity greater than the pump chamber 25 to ensure complete refilling of the pump chamber when the bottle units are restored to the upright position. Thus, it will be apparent that the reservoir 55 is filled by gravity flow of the liquid in the tilted position, and the liquid is transferred to the pump chamber by gravity flow when the unit is restored to the upright position.

It should be noted that a shaft 60 which is affixed to the piston 26 may be mounted off center as seen in FIGS. 1 and 3 so as to prevent the piston 26 and actuator button 14 from rotating to an inoperative position. Alternatively, the trip finger 42 can be made longer and always extend at least partially within the opening 43 so as to maintain alignment of the finger and ensure actuation of the hammer 15. Alternate striking arrangements may be employed for the hammer 15, such as a trip linkage which causes the hammer to quickly strike and quickly release its contact with the vibrator 13 upon depression of the button 14.

The present embodiments of this invention are to be considered in all respects as illustrative and not restrictive.
